Patent JP-S639125-A (JP)
Title: Semiconductor device
Inventor: NAKAGAMI YOSHIMASA
IPC: H01L21/314
Filed: 1986-06-30
Abstract: PURPOSE:To enable the cover film to be prevented from being destroyed by providing a round shape to the portions of the inter-layer insulating film provided on the rear side of a wiring pattern opposite to the wiring pattern edges, thereby preventing stress from concentrating on limited parts of the cover film. CONSTITUTION:If an Al wiring pattern 1 is excessively etched after an inter- layer insulating film 5 is formed, in the vicinity of the portions opposite to the edges 1a of the Al wiring pattern 1, arc portions 5a reaching the inter-layer insulating film 5 surface are formed from the edges 1a in a continuous arc. Since a cover film 6 and resin layer 7 are formed along the arc portions 5a, arc portions 6a are formed in the portions of the cover film 6 opposite to the arc portions 5a, and similarly arc portions 7a are also formed in the resin layer 7. As the arc portions 6a are formed in the cover film 6 in this manner, stress of the cover film 6 escapes along the arc portions 6a as shown by an arrow (b), and as the arc portions 7a are formed in the resin layer 7, stress of the resin layer 7 escapes along the arc portions 7a as shown by an arrow (c), so stress does not concentrate these portions respectively.

Title: Air-flow deflecting device for air conditioner
Inventor: KAWABATA TOSHIAKI
IPC: F24F1/00
Filed: 1979-11-28
Abstract: PURPOSE: To provide an arrangement capable of changing the air discharging direction considerably without increasing pressure loss, by controlling the turning speed of a pair of impellers disposed adjacently to each other for rotation in opposite directions.  
     CONSTITUTION: A pair of through-type impellers 1, 2 are disposed adjacently to each other, so that they are rotated in opposite directions to each other. Air flow produced by one impeller 1 is drawn near to a guide wall 3 but air flow produced by the other impeller 2 is drawn near to another guide wall 4. When these two impellers 1, 2 are rotated at the same speed, the air flow is spread symmetrically from the center. However, when the impeller 1 is rotated at a high speed but impeller 2 is rotated at a low speed, the air flow is deflected toward guide wall 3. On the other hand, when impeller 1 is rotated at a low speed but impeller 2 is rotated at a high speed, air flow is deflected toward another guide wall 4. Therefore, it is enabled to change the air diffusing direction freely or automatically by controlling the turning speed of impellers 1, 2.

Title: Alkaline ion water producing apparatus
Inventor: EBARA TAKASHI
IPC: C02F1/46
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To remove calcium without using citric acid by repeating following processes of supplying a little amount of water to an electrolytic bath by opening or closing a flow rate controlling mechanism for water supply by operating a calcium removal mode switch, changing to a strongly acidic water production, and making the strongly acidic water lingering in a prescribed period in a water discharge pipe. SOLUTION: In the case of removing calcium constituents from the inner face of a water discharge pipe 13, a cleaning setting part 202 of an operation display part 20 is operated. The flow rate controlling mechanism 32 is slightly opened by a controlling means 21 to lead a little amount of water to an electrolytic tank 7. At the same time, the electrode 9 is switched to an anode and the electrode plate 10 to a cathode. At that time, the flow rate ratio of the water discharged out of the anode side is made higher than the wastewater discharged out of the cathode side by a flow rate controlling part 12 to make the strongly acidic water lingering in the anode side. After a prescribed time passes, the flow rate controlling mechanism 32 for water supply and a flow rate adjusting mechanism 33 for water discharge are opened to discharge the lingering water.  These processes are repeatedly carried out. Consequently, calcium adhering to the inner face of the water discharge pipe 13 can efficiently be removed.

Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To obtain a curable resin which gives a cured item excellent in softness and resistances to heat and moisture by subjecting a compound having (meth)allyl groups and a silicone compound having Si-H groups to addition reaction. SOLUTION: Because of the good compatibility with and the smoothness in addition reaction with a silicone compound (B) having Si-H groups, tris(2- propenyl) isocyanurate is preferable as the compound (A) having (meth)allyl groups. A silicone compound having Si-H groups at the silicone chain terminals is preferable as compound B, since such a compound has a good reactivity with compound A; compound B having Si-H groups at both the molecular terminals, e.g. a compound represented by the formula, is preferable, since a cured item having especially good properties is obtained. In the formula, R2 and R3 are each (cyclo)alkyl or aryl; R1 and R4 are each R2, alkoxy, or aryloxy; and n is 0-100. This resin is excellent in compatibility and copolymerizability with a maleimide compound and gives a low-permittivity cured item.

Abstract: PURPOSE:To perform multiple address communication by single-time signal output and to easily resend data in case of trouble a communication control part by connecting plural communication control parts, a shared memory, and a circuit control part to a time-division multiplex transmission line in a multiple address communication system. CONSTITUTION:When a signal is transmitted from a terminal device 21a to communication control parts 23b and 23n, a communication control part 23a stored with equipment identification numbers of those control parts and a data signal temporarily becomes a talker when receiving the time slot address its device, and outputs the equipment identification number (b) and (n), identification number of the shared memory, and data signal.
